A comment on some features of ‘true protection’
评论Greenaway和Milner关于‘真实保护’概念的分析，指出他们因忽略模型某些特征而导致结论不一定正确。
Greenaway and Milner [1987] analyse the concept of ‘true protection’ and reach certain results about the relationship between the change in price of exportables, importables and home good. This note shows that their results are not necessarily correct because they have overlooked some features of their model in their analysis.
